My EE seems to have come down with Body Slime Infection overnight. Just a little slime hanging off her face. I'm getting ready to start the water changes with aquarium salt. I know with some sicknesses the temp the betta is kept in need changed. What temp should this fish be kept in while I am treating her? I have a heater that will keep her about 80, but if it needs to be higher I need to run out and buy one.

I agree with raising the humidity, she should be fine at 80 degrees. The best remedy for body slime is malachite green. Most ick/parasite medications contain malachite green. Pick up some mardel maracide or seachems paraguard, both are effective, make sure to treat exactly as instructed, malachite green is harmful if overdosed
